Nifurtimox has a strong killing effect on bacteria, trichomonas and mycobacteria, candida, etc. that cause female reproductive system infections, but it does not have an inhibitory effect on lactobacilli that maintain the normal ecological balance of the vagina, so the application of Nifurtimox generally does not destroy the flora, but can promote the balance of microecology in the body. It is suitable for vulvar and vaginal infections caused by bacteria, trichomonas, mycobacteria and candida, as well as leucorrhoea and urinary tract infections. Nifurtimox is available in tablet and suppository forms: 1. Tablet: It will be rapidly absorbed by the body after oral administration, but the drug will not pass through the placenta, so Nifurtimox tablets can also be used during pregnancy. It is usually metabolized through the kidneys and excreted in the urine. Since the drug can also be excreted through the milk secreted by women, so avoid taking the drug orally during breastfeeding; 2. Suppositories: The more common in life is the suppositories of nifurtimox, which are generally administered vaginally and mainly absorbed through the vaginal mucosa and will not enter into the milk, so women who are breastfeeding can apply suppositories under the guidance of doctors. It should be noted that the drug must be applied under the guidance of a doctor, and it should be used in a standardized and reasonable manner, not on its own. During the patient’s application of nifurtimox, it may cause stress reactions in the body, such as gastrointestinal reactions and rash reactions. Patients should prohibit drinking alcohol and all drinks containing alcohol during the medication period, pay attention to the regulation of work and rest time, and keep personal cleanliness. Patients who are allergic to nifurtimox are advised to avoid the use of this drug.
